Scott convinces Leonard to go across the street to get candy since their street is only offering fruits and vegetables, but both of them start to feel guilty since Leonard had promised to his mom previously that he wouldn't go across the street.
Meanwhile, after Leonard takes in a stray black cat from out of the rain, Mr. Jolly and Pretty Boy suspect that the stray black cat is a vampire after noticing his supposedly evil and supernatural behavior.
